The dorsal sepals is egg-shaped, 7–9 mm (0.3–0.4 in) long and 2–3 mm (0.079–0.12 in) wide, the lateral sepals 7–9 mm (0.28–0.35 in) long and 5–6 mm (0.20–0.24 in) wide. The petals are lance-shaped to egg-shaped, 5–6 mm (0.20–0.24 in) long and 2 mm (0.08 in) wide. The labellum is pink, thick and fleshy, about 6 mm (0.24 in) long and 3.5 mm (0.14 in) wide.

Taxonomy and naming

Bulbophyllum lageniforme was first formally described in 1904 by Frederick Manson Bailey and the description was published in the Queensland Agricultural Journal from a specimen collected near the summit of Mount Bellenden Ker.[4] The specific epithet (lageniforme) is derived from the Latin words lagena meaning "a large jar or bottle with handles and a narrow neck"[5]:159 and forma meaning "shape", "figure" or "model".[5]:345

Distribution and habitat

The smooth strand orchid grows on trees and rocks in rainforest and in sheltered places in drier forests. It occurs between the Mount Finnigan and the headwaters of the Tully River in Queensland.[2][3]
